7th grade math) I need help for this surface area of rectangular prism pixel art!!
For the method we do:
Top-
Bottom-
Side-
Side-
surface area-
I'm confused what I did wrong since I did 9.3 * 9 which gave me 83.7(including bottom) and when I did the sides, I get 9.3
I added them up and it was incorrect
